Abstract

An improved flexible connector (60) for a circuit breaker. The flexible connector, preferably, comprises a plurality of flexible sheets arranged in a stack. The stack defines an opening (68) having an edge (82) including at least one tab (80) extending inwardly from the edge of the opening. The tabs are adapted to bend so that they make a secure interference fit with a movable contact (12) so that current can flow directly from the movable contact into the flexible connector. A circuit interrupter system is also disclosed.
